摘要
The phase behavior of bimodal molecular weight high density polyethylene(BHDPE) in solid state was investigated.Hildebrand solubility parameters(δ) were calculated for the models of blends of higher molecular weight branch polyethylene(HBPE) with different branch contents and lower molecular weight linear polyethylene(LLPE),by using molecular dynamics(MD) simulations.These 3 values were then used to calculate the corresponding Flory-Huggins interaction parameter(x) between HBPE and LLPE models.In order to b...
